GPS-RTK在工程测量中的应用及常见问题解决方法

Application of GPS-RTK in Engineering Measurement and Solutions of Common Problems

RTK(Real-time kinematic)实时动态差分法是一种新型的GPS测量方法,相对于常规的动态、静态、快速静态等测量方法,实时动态技术(RTK技术)定位速度更为快速准确,克服了传统测量方法中只有事后进行解算才能获取高精度数据,对观测所得数据无法及时进行检核等技术难题。RTK技术采用了载波相位动态实时差分方法,其应用为地形测图、工程放样等各种控制测量带来了新的技术革新,极大地提高了作业效率,是GPS应用的重大里程碑。基于此,论述GPS-RTK在工程测量中的应用、存在问题及相关处理措施。

RTK (Real- time kinematic) is a new method for GPS measurement. Compared with the static,fast static and dynamic measurement methods, the real-time kinematic technology (RTK) is more rapid and accurate. It overcomes some problems in traditional measurement methods, such as we can only get the high accuracy data after the calculation, the observation data can not be detected nuclear and other technical problems. RTK technique employs the carrier phase, is a major milestone in the application of GPS. It brings new dawn for the engineering sample release, topographic mapping and various of control measurements.The working efficiency of the field work has been gready improved. Based on this, the application of RTK in engineering measurement, the existing problems and related treatment measures were discussed.
